  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
    public class StrictNumberFormatter
extends javax.swing.text.NumberFormatter
    Experiment to work around Issue #1183-swingx: NumberEditorExt throws exception on getCellValue. Remaining issue: no visual error feedback if the expected number type exceeds its range.
